Note that all further changes will be noted in a separate file
(SvnLog).
2004-04-08 Deepayan Sarkar
* R/qq.R, R/qqmath.R, man/qq.Rd, man/qqmath.Rd: changed default
behaviour of qq and qqmath to use actual data instead of sample
quantiles. The new behaviour is different from the corresponding
S-PLUS functions, but is closer to analogous base functions qqplot
and qqnorm
2004-03-22 Deepayan Sarkar
* R/print.trellis.R: changed behaviour of skip
* man/xyplot.Rd: updated docs for skip
2004-03-19 Deepayan Sarkar
* utilities.3d.Rd: removed palette.shade from docs
* panel.cloud.Rd: adjusted docs for panel.3dwire's shade.colors arg
* latticeParseFormula.Rd: fixed docs for drop
* R/*.R: added drop.unused.levels as a high-level argument to
xyplot etc. The earlier behaviour was a trellis.par.get-table
setting, but that doesn;t make sense because this is not a display
parameter
2004-03-17 Deepayan Sarkar
* panel.functions.Rd: added panel.rug in docs
* lset.Rd: added link to trellis.device
2004-03-13 Deepayan Sarkar
* panel.cloud.Rd: added note saying x,y,z could all be matrices
* cloud.Rd: added docs in wireframe for parametrized 3-D surfaces
2004-03-12 Deepayan Sarkar
* DESCRIPTION: updated version
* tests/test.R: minor changes
* demo/lattice.R: added wireframe sphere
* R/densityplot.R: fixed default prepanel function to not throw an
error (in density()) when panel has only 1 point
* R/common.R: modified latticeParseFormula to keep matrices
unchanged (so that a formula of the form matrix ~ matrix * matrix
can be used in wireframe)
* R/cloud.R: added (way cool) changes to allow wireframe to render
3-D surfaces parametrized on a grid (e.g. a sphere)
* man/update.trellis.Rd: added mention of legend
* man/panel.pairs.Rd: fixed synopsis
* man/print.trellis.Rd: fixed grid links (hopefully)
2004-03-08 Deepayan Sarkar
* miscellaneous.R: added a col.line arg for lplot.xy to
distinguish between color for lines and points (not that it
matters here, but panel.xyplot and panel.superpose make the
distinction, and it's easier to just pass it down here)
* cloud.R, levelplot.R, scales.R, settings.R, update.trellis.R,
zzz.R: many improvements to cloud and wireframe, plus misc changes
2004-03-05 Deepayan Sarkar
* tmd.R: tmd simplified using update(), fixed potential xlab/ylab
bug
* miscellaneous.R, print.trellis.R, update.trellis.R:
obscure improvements to axis setting usage and update method
* R: bunch of updates, mostly dealing with fonts (fontfaces,
fontwidths) and labels (main, sub, xlab, ylab)
2004-03-03 Deepayan Sarkar
* man/xyplot.Rd: added docs for perm.cond, index.cond; updated
other parts
* R: bunch of fairly major changes, including code reorganization
and addition of features, too numerous to list. A summary of the
changes is available in inst/Changes
2004-03-02 Deepayan Sarkar
* man: doc updates mostly to ensure R CMD check passage
2004-02-14 Deepayan Sarkar
* xyplot.Rd: added entry for par.settings, corrected statements
about subscripts
2004-02-13 Deepayan Sarkar
* xyplot.Rd:
added note on panel.number and panel.counter arguments. Has a related
brief and oblique mention of the conditioning variable permutation /
reordering stuff. Not sure what the best place to put a more detailed
description is.
2004-02-10 Deepayan Sarkar
* man/Lattice.Rd: wireframe is no longer slow, so removed
statement to that effect. Replaced S-Plus with S-PLUS
2004-02-08 Deepayan Sarkar
* man/print.trellis.Rd: added warning not to use aspect != "fill"
with explicit panel.width and panel.height
2004-02-05 Deepayan Sarkar
* man/xyplot.Rd, cloud.Rd: fixed errors of the form
\link{\code{stuff}}
2003-12-20 Deepayan Sarkar
* DESCRIPTION, NAMESPACE : made changes to deal with package
reorganization in R 1.9.0-pre. Some other files changed as well
(mostly dealing with loess.smooth, which is now in stats)
2003-10-17 Deepayan Sarkar
* R/axis.R : added trim = TRUE in format() when calculating axis
tick labels. Without this, labels often had leading spaces,
causing a visible 'right shift' (reported by Patrick Connolly).
2003-10-10 Deepayan Sarkar
* R/ : split common.R into common.R, axis.R and scales.R
2003-10-09 Deepayan Sarkar
* R/levelplot.R: Fixed panel.levelplot bug where nothing was drawn
if a panel contained only one unique value of x/y (reported by
Wolfram Fischer).
2003-09-15 Deepayan Sarkar
* R/miscellaneous.R: added some code to handle cex when pch =
character, using new grid feature. However, grid has a bug when
pch - numeric, so there's still a workaround in place, which
should eventually be removed. This overrides related changes on
2003-09-03
* man/panel.pairs.Rd: added doc for prepanel.limits, pscales
* tests/test.R: added code with splom pscales weirdness
* R/splom.R:
earlier interpretation of pscales was ambiguous. Changed to make
specification of limits, at and labels consistent. See panel.pairs
docs.
* man/splom.Rd:
moved bulk of pscales doc over to help page for panel.pairs
2003-09-05 Deepayan Sarkar
* splom.R:
added a prepanel.limits argument to panel.pairs to allow custom axis
range calculations for each variable
2003-09-03 Deepayan Sarkar
* miscellaneous.R:
lplot.xy modified to use grid.text when pch is non-numeric. This
would allow pch like pch = 'string' or pch = expression(sigma). This
feature would disappear in the future.
2003-08-29 Deepayan Sarkar
* levelplot.R:
the older contourplot routine went horribly wrong when there were NA's
in the z-values. This has now been addressed with a slightly crude
hack: all z-NA's are now replaced by min(z, na.rm = TRUE) for the
contour drawing routine. This may cause inaccuracies near the
"border", but should be OK in most real-life cases, where the non-NA
part should be a largish connected piece, with a fairly insignificant
boundary.
This incidentally fixes another bug, apparent when the at vector
does not cover the full z range (colors used to be recycled
instead of leaving blank spaces)
2003-08-22 Deepayan Sarkar
* settings.R: (canonical.theme) also added clip option for the strip
* print.trellis.R:
clipping for panel and strip now determined by trellis setting "clip"
* settings.R:
added a clip = list(panel = TRUE) to the list of valid settings
2003-08-21 Deepayan Sarkar
* levelplot.R (panel.levelplot):
shrinking had problems for constant z values within
a panel (diff(range()) = 0, leading to division by 0). Also, it turns
out that shrinking was being done based on range of z within each
panel, not the overall data frame. This could be misleading, so
changed.
2003-08-20 Deepayan
* common.R (calculateAxisComponents): the format argument renamed
to format.posixt (to avoid confusion with the format
function). More importantly, in the "plain numeric" case,
as.character(at) replaced with format(at). So now at = c(1, 1.5,
2) will be labeled as c("1.0", "1.5", "2.0") instead of c("1",
"1.5", "2"). Both changes suggested by Tom Short.
* common.R, settings.R, zzz.R: Supplemental changes related to
NAMESPACE. Also renamed man/lattice-internal.Rd to
man/lattice-internal.Rd.foo --- this is ignored by R CMD scripts,
but has been retained as a possibly useful reference for internal
(unexported) functions.
2003-08-05 Deepayan
* zzz.R: NAMESPACE changes (due to Prof Ripley)
* print.trellis.R:
changes associated with NAMESPACE (actually moving .lattice.print.more
to an environment)
* NAMESPACE: added NAMESPACE file
* R/zzz.R, R/print.trellis.R, R/settings.R: changes related to
NAMESPACES (actually due to moving a couple of global variables to
a new environment (see R/zzz.R) ), due to Prof Ripley. Also
simplified trellis.par.get() a bit.
2003-05-31 Deepayan Sarkar
* bwplot.R, cloud.R, miscellaneous.R, xyplot.R:
changed order to sort.list where appropriate
2003-05-29 Deepayan Sarkar
* levelplot.R: added na.rm = TRUE to min in min(abs(slopes))
because sometimes slopes can be NaN. Also, added graphics
parameters for panel.levelplot labels
2003-05-24 Deepayan Sarkar
* panels.R:
added a function called panel.curve, similar to curve() in base.
* R/panel.functions.Rd: added docs for panel.curve
* man/panel.pairs.Rd: added doc entry for 'panel.number'
2003-05-22 Deepayan Sarkar
* tests/scales.R: added output file name
* tests/MASSch04.R: changes a call to title() to main=
* tests/test.R: added output file
* tests/dotplotscoping.R: added output filename
2003-05-22 Deepayan Sarkar
* DESCRIPTION: updated DESCRIPTION
* man/panel.pairs.Rd: added doc entry for 'panel.number'
* R/common.R (limits.and.aspect): Following up on a report by
Kevin Wright, I discovered that the presence of blank panels
(either by skip or due to layout specifying more panels than were
actually there) caused problems in calculating factor levels
(adding an extra NA level). This should be fixed now. Also,
handling of xlim=list(...) improved in cases with skip (not that
anyone is ever going to use it).
2003-05-22 Deepayan Sarkar
* splom.R:
panel functions can now optionally ask for a panel.number argument,
which would be supplied as an argument only if the panel function has
such an argument. Unfortunately, this was not working as intended in
splom, because of the unusual nature of the panel/superpanel
arguments. This has been fixed.
2003-05-19 Deepayan Sarkar
* man: fixed minor doc problems to pass R CMD check
2003-05-18 Deepayan Sarkar
* R: Almost all files updated to fix bugs related to the scales
argument --- limits inside scales had a bad bug which is now
fixed, also added and improved support for multiple (as lists)
limits, at, labels. axs = "i" should also work.
* tests: new tests added
* R/miscellaneous.R: modified lsegments to accept x0, x1 as well
as x1, x2 (a la S-PLUS).
2003-04-10 Deepayan Sarkar
* man: Documentation updates
2003-03-26 Deepayan Sarkar
* bwplot.R, common.R, panels.R, print.trellis.R, zzz.R:
some bugfixes, added MASS ch04 script to tests
2003-03-26 Deepayan Sarkar
* print.trelis.R: fixed problem with expressions as axis tick
labels when relation = "same". Reverted back to using (slower) old
code in colorkey because of (grid?) bug in new version.
* common.R: added code in latticeParseFormula to convert matrices
to data frames (for splom and parallel) before subsetting.
2003-03-15 Deepayan Sarkar
* common.R:
fixed some problems when outer and conditioning variables interact
* print.trellis.R: fixed y-axis scales drawing
* common.R (latticeParseFormula):
added argument outer=FALSE. When outer = TRUE,
variables separated by + (when multiple = TRUE) are made into a
conditioning variable instead of grouping variable
* several: updated support for multiple LHS/RHS in formula,
auto.key, outer
2003-03-14 Deepayan Sarkar
* levelplot.R: changed prepanel functions to handle factors
gracefully. Fixed problem with unequally spaced grid
points. Improved contourplot labelling. New argument shrink in
panel.levelplot, allowing rectangle dimensions to be proportional
to height. (Many of these were actually done much earlier, but
committed now)
* bwplot.R:
fixed some problems with processing of formula in dotplot etc before
calling bwplot
* common.R: removed latticeAsFormula, no use
2003-03-14 Deepayan Sarkar
* print.trellis.R (print.trellis):
Among other things, a rewrite of how axis ticks and
annotation are drawn (mainly how the parameters translate to physical
dimensions). The tck, rot and cex components of scales can now be
length 2 vectors, for bottom/left and top/right scales. tck can be
negative, giving ticks inside panels. panel functions with a
... argument are now passed a variable called panel.number, giving the
sequence number of the panel (not sure what happens when skip is
non-FALSE)
* plot.shingle.R:
modified plot.shingel to make tck, cex and rot 2-vectors
2003-03-13 Deepayan Sarkar
* bwplot.R: added code to panel.barchart (also panel.dotplot) to handle
groups. Substantially changed the way arguments are processed in
barchart, dotplot and stripplot before being passed on to bwplot. When
y is missing, and x has non-null names(), names are used as the y
variable.
Also added changes necessary to enable multiple LHS and RHS is formula
with allow.multiple = TRUE.
2003-03-13 Deepayan Sarkar
* common.R (construct.scales):
made changes so that cex, tck and rot can now be
length 2 vectors in scales, affecting scales at the bottom/left and
top/right of panels respectively. Associated changes in print.trellis
later.
2003-03-13 Deepayan Sarkar
* settings.R (trellis.device):
Changed the default for the theme argument from NULL
to getOption("lattice.theme"), which can be either a list, or a
(possibly quoted) function, which when called will return a list.
2003-03-09 Deepayan Sarkar
* splom.R (panel.pairs):
the pscales argument didn't work when it was specified
as a list. Fixed.
2003-03-07 Saikat DebRoy
* common.R (latticeParseFormula):
Compute a new element of the answer, subscr, if subscripts=TRUE.
2003-03-07 Deepayan Sarkar
* common.R (latticeParseFormula):
added a subscripts = FALSE argument, which is
not used anywhere yet.
2003-03-05 Deepayan Sarkar
* print.trellis.R (print.trellis): added two new arguments to
print.trellis;
panel.height = list(1, "null"),
panel.width = list(1, "null"),
which can be used to specify explicitly the dimensions of each
panel in terms of grid units. Any unit is allowed as long as it
does not need a 'data'. Not too difficult to add that, but
probably unnecessary. Behaviour is undefined (well, it is defined,
but I don't want anyone to count on it) when aspect is not "free"
in the object being printed. Docs not updated yet.
2003-03-05 Deepayan Sarkar
* print.trellis.R (draw.colorkey): Colorkey changed to use the
vector fill gpar when drawing rectangles. This means all
rectangles are drawn at one go, hence less things to grid.pack(),
hence faster when lots of cuts in levelplot/wireframe.
2003-03-04 Saikat DebRoy
* common.R (latticeParseFormula):
Fix concat() to handle shingles correctly.
2003-03-03 Saikat DebRoy
* R/common.R (latticeParseFormula):
Allow the possibility of having multiple
variables in LHS or RHS of the model formula (eg. y1+y2 ~ x1+x2).
2003-03-03 Saikat DebRoy
* R/common.R (latticeParseFormula):
Use the environment of the model as enclos
argument in calls to eval().
2003-02-24 Deepayan Sarkar
* R/zzz.R: Restructured .First.lib following suggestions from
Prof Ripley. Changed library(grid) to require(grid), with an
error message if that fails.
* R/levelplot.R: xlab, ylab, etc in contourplot was not passed on
properly to levelplot. Fixed.
2003-01-30 Deepayan Sarkar
* R/densityplot.R: changed prepanel.default.densityplot to return
range instead of some-stupid-thing else when a groups argument is
given.
2003-01-16 Deepayan Sarkar
* R/settings.R: changed trellis.par.get so that when called with
no device open, it starts the default device a la print.trellis
2003-01-15 Deepayan Sarkar
* R/levelplot.R: levelplot used to calculate wx and wy, which was
not a good idea since this should have been done inside the panel
and prepanel functions. The prepanel function has been rewritten,
fixing a bug, but some more reorganization still needs to be done.
2002-12-18 Deepayan Sarkar
* R/miscellaneous.R: fixed problem the with 'adj' argument in
ltext (used to ignore second component, PR#2380). added 'pos'
argument as in text. No offset yet, though.
* R/panels.R: Changed panel.superpose to pass groups and
subscripts to panel.groups (PR#2377). Not very obvious how groups
might help, but I guess more information is better than
less. Also, several other panel functions didn't recognize the
col.line argument, this was fixed.
2002-12-15 Deepayan Sarkar
* R/common.R: The changes in lattice 0.5-0.6 added some code that
gave bad results when some panels had all NA's. That hopefully
fixed.
* R/miscellaneous.R: lplot.xy used to call grid.text instead of
grid.points when pch was a character. Fixed this.
* R/print.trellis.R: draw.key failed when lines component had
type='b', because of a missing pch. Fixed this.
* R/levelplot.R: Minor fix related to changes in grid.
2002-12-06 Deepayan Sarkar
* R/settings.R: added warnings and error messages in
trellis.par.get/set when no active device, and when value in
trellis.par.set is not a list.
* R/trellis.par.get.Rd: rewrote some things
2002-11-16 Deepayan Sarkar
* R/common.R: added arguments have.log and logbase to
calculateAxisComponents()
* R/print.trellis.R: made changes to use above changes
2002-10-28 Deepayan Sarkar
* R: Hmm, lots of changes made without any log entries. Should be
more careful ! Anyway, renamed inst/README to inst/Changes, and
added a brief overview of changes in lattice 0.6 . Also made some
documentation updates. Changed version to 0.6-6, ready to upload.
2002-01-10 Deepayan Sarkar
* R: Too many changes to list, mainly in print.trellis and
documentation.
2001-08-08 Deepayan Sarkar
* R/levelplot.R: Implemented preliminary levelplot (no contourplot
though). Also a version of cloud, though no support yet for nice
axes/arrows and stuff (does allow panel.superpose though). Again,
no plans of implementing wireframe in the near future.
2001-08-08 Saikat DebRoy
* R/common.R:
Added support for 3d formulae in latticeParseFormula
2001-07-26 Deepayan Sarkar
* R/Lattice.Rd: Included llines, lpoints etc for easy adaptation
of existing Trellis code. qq() changed to as it should be, should
now work with tmd().
2001-07-12 Deepayan Sarkar
* R/Lattice.Rd: Major redesigning of existing functions. Mainly
by collecting common code into a few functions and hence
making individual functions easier to handle. Code should now
be fairly readable. Also, more or less good support for log scales
and key (I hope). Not much checking done yet, there may be bugs.
Documentation might be out of step at places.
2001-05-06 Deepayan Sarkar
* R/tmd.R: Name changed from trellis to Lattice. Prelilminary
changes to account for change of Lattice to Grid made. New
functions rfs, oneway, qq (not final), qqmath, tmd, plot.shingle,
update.trellis. Documentation more or less clean.
2001-04-19 Deepayan Sarkar
* R/trellis.R: lots of changes. Introduced trellis objects.
Print method for trellis objects. Implementation now includes
barchart, bwplot, densityplot, dtplot, histogram, stripplot,
xyplot, splom and parallel (and excludes piechart(will probably
remain that way), qqmath, qq, timeplot(?), contourplot,
levelplot, wireframe and cloud). Cleanup, documentation etc.
2001-03-22 Deepayan Sarkar
* R/trellis.R: added splom and some brief documentation for splom
2001-03-02 Deepayan Sarkar
* R/trellis.R: dtplot (dotplot) implemented. Probably has lots of bugs.
Some documentation, including example for dtplot (same as usual dotplot example).
2001-03-02 Deepayan Sarkar
* R/trellis.R: updated bwplot (with the new layout structure)
